bros if my house no space put compressor liao, any good aircons to recommend?
for non-inverter aircon, that is very true... the outdoor compressor unit doesnt have a variable rotation speed. Even if you turn on one fancoil and two fancoil, it consumes the same...
If you want the prove, you can always check your outdoor electric meter.. use stopwatch to count how many seconds it take to make 1 full rotation with one and two fancoil on for Non-inverter aircon
the power consumption might increase if 2 fancoil. reason is becos the room temp and time taken to the desired temp for the 2 rooms is different.
Have you tried counting the meter?
I have tried, and they are the same when you just turn on the aircon..
It might be different if one room set at 25 and another set at 16.... lower degree will force the compressor to work non stop
haha... we hav 2 diff sets of results here!
when i asked 2 salesman at courts, i have 2 diff answers same as u 2 as well!
So if 2 rms hav exactly same parameters, eg same RM temp, same desired temp set, same RM size etc, the power consumption is same for using 1 or 2 fancoil rite?
Of course in real life can't be exactly the same....but with this knowledge, when I on my RM Aircon, I will ask my parents on as well since the power consumption is not 2 times more, prob only 20% more!
i would've to agree with chunlianghere.
when the desired temperature is reached, the compressor shuts off.
therefore as chunlianghere already stated, the energy needed to cool one room to desired temperature should not be the same as for two rooms.
Obviously when the non-inverter compressor is running, it consumes same amt of power since as stated by sentosaubin it only has one speed (that explains about the counting seconds for each rotation). However, sentosaubin should checked the difference in times the compressor ran to cool one and two rooms.
no offense to salesman out there, but some of them aren't very technical.
I was comparing day by day when the 2 RM and 1 RM with aircon switched on, and the difference are so negligible.... like 20 kW and 19.5 kW per day... so 20% approximation by shevchenko wont be that far off
hm... interesting.
how did you measure the electrical usage?
so in this case, for a non-inverter air-con, the extra electrical energy it took to cool a space twice (2 rm) as large (1 rm) is 20% ?
actually to wat i tink, the extra electrical for 2 rooms would be the fan coil.
if using larger fan coil, than it could be ~1.5 times more electrical than normal 1 room.

sorry, i dun understand wat u mean by using a larger fancoil...
so i tink we can conclude that for non inverter aircon, assuming both same size fancoil, temp etc, the pwr consumption is probably abt 20% more for turning on 2 fancoils compared to turning on 1 fancoil

You don't know how to measure? The electric meter is just outside... unless yours are concealed, then i have nothign to say.
Assuming the capacity of the compressor is 14000 btu (system 2, non inverter).
If turn on 2 aircons, it should be 7000btu x 2 right?
If turn on 1 aircon, it should be 14000btu right?
If it is true, then the desired temp should be reached faster if you turn on only 1 room.
